If w = 7 feet, x = 6 feet, y = 13 feet, and z = 8 feet, what is the area of the object?
Answers
Answer:
The Area is: 84ft
Step-by-step explanation:
multiply "Y" and "X" and you get 78ft.
"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.
"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2
2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.
78+6=84.

Their sum:
(2x-3)+(3x+2)2x + 3x -3 + 25x - 1Factor the trinomial 6x²-5x-6, then find the sum of the factors .
Given : -An equation = 6x² - 5x - 6To Find : -Sum of their factors .Concept : -This question belongs to factorising the trinomial with the help of different methods such as middle term splitting .
Solution : -[tex] \longrightarrow \: 6x {}^{2} - 5x - 6[/tex]
Now , by splitting the middle term that is - 5 x :
[tex] \longrightarrow \: 6x {}^{2} - 9x + 4x - 6[/tex]
Now , taking 3x and -2 as common :
[tex] \longrightarrow \: 3x(2x - 3) + 2(2x - 3)[/tex]
So ,
[tex] \longrightarrow \: ( 3x + 2 ) ( 2x - 3 )[/tex]
Therefore , factors are ,
( 3x + 2 )( 2x - 3 )In the question we have ask to find the sum of their factors . So adding them ,
3x + 2 + 2x - 35x - 1Therefore , 5x - 1 is the sum of the factors .

A figure is shown.
What is the value, in degrees, of xx?
Answers
Answer:
x = 44.3
Step-by-step explanation:
Knowing that the given figure shows a supplementary angle
⇒ Note that: Supplementary angle= 180 °
Since it already given the other two number
The equation is:
43 + 92.7 + x = 180
Adding both number together : 43 + 92.7
135.7 + x = 180
Subtract 135.7 from both sides
135.7 -135.7 +x = 180-135.7
x = 44.3
Hence, the value in degrees of x = 44.3 °

△ABC has interior angles with measures x°, 100°, and 70°, and △DEF has interior angles with measures y°, 70°, and 50°.
Using the given information, which statement is true?
The two triangles are not similar because x≠y .
The triangles are similar because they each have an interior angle with a measure 70°.
The two triangles are not similar because the interior angles are congruent but the side lengths are different.
The two triangles are not similar because y = 60 so it is impossible to have three congruent angles.
Answers
Answer:
Now, △DEF has interior angles with measures y°, 70°, and 20°.
By using angle sum property,
Now, we can say that,
"The two triangles are not similar because x≠y"
As one angle of measure 70 degree is common in both the triangles.
If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.
Therefore, the two triangles are not similar because x is not equal to
Step-by-step explanation:
Answer:
the triangles are not similar. If they were, they would have the same angles.
The interior angles are not congruent. We can rule out choice B and C.
Just because they have one equal angle does not make them similar. We can rule out D.

Now, add 3
[tex]25 + 3 = 28[/tex]
Next, subtract 1
[tex]28 - 1 = 27[/tex]
Now, you must divide, because the line under the first equation represents division, or a fraction. For this case, division. Before dividing your result, 27, by y, the second equation, you first want to solve equation 2, y.
[tex]\frac{18}{2} = 9[/tex]
Lastly, divide x by y, 27 divided by 9

The diameter is 4. We divide the diameter by 2 to get the radius.
4 ÷ 2 = 2
Substitute for the radius.
A = 3.14 × 2²

Answer:

Step-by-step explanation:
[tex] \sqrt{4 {}^{2} + 4 {}^{2} } [/tex]
= 5.65685
= 5.66 (3 s.f.)
By using the Pythagorean theorem, we will see that the length of DF is 5.7 units.
How to get the length of DF?
We can make a right triangle with the sides: DE, FE, and DF.
Such that we know that:
DE = FE = 4
These two are the cathetus of the right triangle.
Then DF is the hypotenuse.
Now, remember the Pythagorean theorem, it says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, then we have:
(DE)^2 + (FE)^2 = (DF)^2
4^2 + 4^2 =(DF)^2
√32 = DF = 5.7
The length of DF is 5.7 units.
